CAR CONSTRUCTION.

Specification of Letters Patent.

Application led .Tune 1, 1914. Serial No. 842,279.

has foritsobject to provide any improvedv superstructure for cars, theskeleton framing 'of which can be made entirely of metal,

Vwhich will be structurally simple, light and strong, which can-bemanufactured at low cost, and which'will also be very compact, so thatthe car will have a maximum inside -width as compared with its outsidewidth.

Another object of the invention is tor pro- .support for the roofplates, or may serve as a support for'carlines when a roof having;

separate transverse members is desired.

' A further object of the invention is to provide a novel connectionbetween the side and end top plates ofthe car. v Y In the practice of myinvention, I contemplate the use of a metallic underframe, such as isused in standard ractice, having the usual center and side sills,holsters and crossbearers, end sills, etc., combined with theconstruction of my invention tofattain the aforementioned objects.

The .inventiony is illustrated, in a preferred embodiment, in thelaccompanying drawings, wherein i y Figure 1 is a side elevational viewof a portion of a box car-constructed in accordance with the invention;Fig. 2 is a ycross sectional view ,of a portion of the width of the cartaken on the line 2-2 of Fig. 1; Fig. 3 is a side elevational view, onan en- [arged scale, of a portion oftheside framing of the car; and Fig.4 is a cross sectional view taken4 on the line 4 4 of Fig. 3. Referringmore particularly in detail to the drawings, in which like referencecharacters refer to like parts in the several figures, in which- 1indicates the center sills, 2 the side sills,

3 the holsters, 4 the crossbearers and 5 the end sills, all of whichmembers may be of any preferred construction. Y I

6 indicates the side top plate which is formed ,of substantially Y shapein cross section and which extends preferably from end to end of thecar. This side top plate preferably comprises parts 7 and 8, which partsare preferably of angular form. The part 7 is provided with an outwardlyeX- tending flange 9, a vertical .leg portion 10 and an inclinedintermediate portion 11, and the part 8 is provided with an inwardlyextending flange' 12, a vertical leg portion 13 and an intermediateinclined portion 14, which leg portion 13 may be connected with the legportion 10 of the. part 7 by rivets or lany other suitable means. Whenthe parts 7 and 8 are secured in the manner just described, the inclinedportions 11 and 14 diverge upwardly and are adapted to strengthen andstiffen the side top plate, as av whole, for its full length. To furtherstrengthen and `stifi'en the side top plate, and to further `tie theparts 7 and 8 together, a member 15 is provided which may be connectedwith .the flanges 9 and 12 of the parts 7 and 8. The end top plate 16may be of any suitable form, but as shown in the drawings preferablycomprises a member of'Z kform in cross section, and eX- tends forsubstantially the full width of the car and may be connected with theside top plate 6 lby brackets or angularmember 17. This end plate 16 mayif preferred also be nade of the same construction as that of the sidevtop plate 6.

`18 indicates the roof plates which may be secured to the side top plate6 by rivets or other suitable means, said securing means being alsoadapted to secure the member 15 `to the parts 7 and 8. In the drawingsaroof has .been shown which comprises plates 1S having integral carlines,but it will be understood that separate carlines and roof plates may besecured to these side plates. If desired, the member 15 of'the side topplate 6 may be dispensed with and the roof plates or carlines secureddirectly to the flanges 9 `and 12 of the side plate.`

The vertical posts 19, diagonal posts 20 and the end posts 21 may be ofany suitable form, but as shown in the drawings are preferably of Zsection. To these posts thel sheathing 22 of the car is secured. The

side posts 19 and 2O extend for substantially the full height of theside wall and at their bottom portions are secured to the side sill 2and at their top portions are secured to the leg portion of the side topplate 6. TheY end posts 21 at their-bottom portions may be secured tothe end sill 5 and at their top portions may be connected with the endplate 16 by members 23.

I do not wish to l1m1t the invention to the exact construction shown inthe draw. ings, for it will be apparent to those skilled part and a roofresting on said plate.

- 2. A car superstructure construction comprising a plurality of parts,portions of said parts diverging upwardly, a member extending across andconnecting said parts and a roof secured to said member.

. 3. A car superstructure part of Y shape in cross section, a plateextending across and connected with said part and a roof resting onsaidplate.

4. A car superstructure part of Y shape in cross section having lateralflanges, a plate extendingacross said part and secured to said flangesand a roof secured to said plate and flanges.

5. A car superstructure part of Y shape in cross section having lateralflanges, a

4member secured to said flanges,I and a roof adapted to' rest on and besecured to said member.

6. 4In a railway car, the combination with a Y shaped top plate havinglateral flan es, of posts secured to said top plate, a mem er secured tosaid flanges and a roof adapted to rest on said member and be secured tosaid top plate and member.

7. In a car, a superstructure part of Y shape in cross section, a plateextending across and secured to said part, a roof resting on saidplate,`and means for securing said roof to said part and plate.

8. In a car, the combination with the superstructure, of top platesforming parts of said superstructure, said top plates each comprising apluralityjof connected upwardly diverging parts, a member connectingsaid parts and a roof carried by ,saidv plates and members.

9. In a car, a Y shaped superstructure part having lateral flanges, avplate connecting said flan es, a roof and means for securing said rooto said plate and flanges.

10. In a car, a Y shaped top plate having lateral flanges, membersconnecting said flanges, and a roof resting on said members.

. 11. A car superstructure part comprising a member having a lowervertical leg portion and upper diverging flanged portions, a memberextending across and secured to said flanged portions and a roof restingon said member. Y

12. A load confining car wall structure comprising a Y shaped top plate,a plurality of posts secured to said top plate, a member extendingacross said to plate and a roof carried by said plate an member.

13,'A load confining car wall structure comprising a Y shaped top platehavin lateral flanges, a plurality of posts secure to said` top plate, amember secured to said flanges, and a roof secured to said flanges andmember.

In testimony whereof I affix my signature in presence of two witnesses.
